General PET Cardiac Workflow

General PET Cardiac Workflow step by step

General PET Cardiac Workflow Nuclear Medicine - PET - Purpose: This step by step document is to assist the PET technologist with the basic steps in the acquisition, reconstruction and display of the PET cardiac study. Common Radiopharmaceuticals Used in Cardiac Perfusion Imaging 1. N 13 Ammonia  Cyclotron produced  See ASNC Imaging Guidelines for patient preparation and dosing  Can be used in Myocardial Blood Flow (MBF) evaluation 2. Rubidium 82 (Rb82)  Generator produced  See ASNC Imaging Guidelines for patient preparation and dosing  Can be used in Myocardial Blood Flow (MBF) evaluation Common Radiopharmaceuticals Used in Cardiac Viability Imaging 1. F 18 FDG  Cyclotron produced  See ASNC Imaging Guidelines for patient preparation and dosing  Cannot be used for Myocardial Blood Flow evaluation.

Build your protocol accordingly. PET Acquisition: Start of acquisition is dependent on the type of radiopharmaceutical used and if MBF eval- uation is going to utilized. If you are planning to preform MBF evaluation, make sure you Siemens Healthineers Services Page 2 of 4 © Siemens Healthcare GmbH, 2017 Job Aid | General PET Cardiac Workflow Effective Date: 8/24/2016 | |695 have the software available to do so. If you have the software, check the the help manual for the recommended number of frames dynamic frames needed for MBF calculation. Fusion: Upon completion of the PET acquisition, you should have both a non attenuated PET cardi- ac series and a low dose CT series available. Load the low dose CT and the NAC series into your fusion application. Check to ensure that the PET cardiac series is aligned correctly with the cardiac muscle from the CT. Use the brightness and mixing ratio tools to assist with the process. If necessary, move (but don’t rotate) the PET image into the correct prosition. Save as a new matrix for reconstruction. Create a savescreen of the image for quality assurance and save with the patient study. CAN, COC.

This workflow should be followed for both the stress and rest studies.
